Access control with Arduino + Keypad 4x4 + Servo

Hi guys, I bring a new instructable for arduino, the control access with password, 4x4 keypad and a servo.

We will use the Password and Keypad librarie for arduino, besides using the servo library, but this project can also be modified by changing the servo, a motor reley or motor stepper, or any other ideas ...

This project can be used in different cases, for doors, Servo action, etc.. Here is the link of the video on youtube to see how it works, then explain step for the armed : D

Step 1: The parts for the project

We will need this parts for the proyect:

Arduino UNO or similar ($29.95)
http://www.sparkfun.com/products/11021

Servo motor - Large ($12.95)
http://www.sparkfun.com/products/9064

KEYPAD 4X4 (or similar) ($7.79)

Proto Board  ($9.58)

Breadborad jumper wire pack ($10.59)
http://www.olimex.cl/product_info.php?cPath=21_138&products_id=872&product__name=Breadborad_jumper_wire_pack

Four resistor of 910 ohm

One resistor of 1k

I made one of this kind and when I was testing there was a power failure and I had to be out till I got my spare keys.

The BYTE term seems to be invalid for Arduino 1.X, what version did you use?
I'm trying to convert. Can you update this Instructable? or add updated code?
Thanks

[nyatuv]

can i use arduino mega?

[ilovewebkinz]

could you use an ir remote insted of a keypad if possible a code too thanks.

Hi! Nice instructable! but the link to the password library doesn't work. here's correct:

[Verkyn]

Hi Sir we are making this arduino project and we would like to do it in a 3X4 keypad because there is no available 4x4. If we would order outside the country it will take much time. We would like to ask you if you a have a program of a 3x4 access controller we urgently need it. Thanks a lot it would be a big help for us. :)

[e-mail] i forgot to attached my email tnx :)

[tolstoyan]

i need the codes for 4x3 wahahhahaha
nice instruction by thw way :)
i also dont know how to change the password? do i have to type my desire password to the code? teach me!!! hahahah im new to arduino hehehe tnx :)

[Lectric Wizard]

sorry ment 910 ohm resistor

[DiogoB13]

hi, can u give some advice how to start a timer when the password is true? i´m trying but still cant( new at the arduino).

[hiphopapotomas]

Hello, How would the programming differ if a 4X3 keypad were used? I dont really want mine to have the ABCD, but this is a great instructables.
Thanks, Austin

[davila1]

how do i change the password, by the way NICE TUTORIAL

[camilo.n1012]

Hi davila, to change the password, please go to line 5 of the code, which states Password password = Password ("your_password"); . Good luck !

[davila1]

thanks a lot keep doing this staff

Hey Camilo, thanks for the instructable. But I can't seem to get it working. The Servo (MG995) just goes on and off for a few seconds and then just off and nothing else happens until I restart the Arduino. I'm using an Arduino Diecimila and a membrane 4x4 keypad.

Thanks!!

[camilo.n1012]

Hi Stevie, double check grades you need for your project, if you want that rotation is longer or shorter you have to go to the judgments myservo.write () and set the required value. Tell me if you have more problems. Good Luck

[tsoumelee]

Hi, do you have a failsafe mode in the code (in case of a blackout)? Thanks!

[camilo.n1012]

Hi, if you mean a fail-safe mode for a apogan in the arduino code is not very convenient, the best In This case, is to put a batery and connected to Arduino, if you have it connected to AC power you put a diode and put the battery.

Good luck

[electrodragon]

nice project, but just want mention one thing, the key pad looks too big, get a membrane one so you can stick it on the wall, like this, will be much nice look.

[camilo.n1012]

Hi, is a very good idea, just need to change the keypad code and change the position of the pins on arduino and I can use a keyboard membranous like this: http://www.olimex.cl/product_info.php?cPath=55_96&products_id=532&product__name=Teclado_de_Membrana_12_teclas_con_conector.

If you need the code for a 4x3 keypad just tell me and publishes :)

[traisjames]

What do you use to make the wiring diagrams?

[camilo.n1012]

Hi, i use the Fritzing, you will download here: http://fritzing.org/download/

[Lectric Wizard]

very usefull Instructable !! Just one question, should there be a 1k resistor fron pin 4 of pad to pin 9 of Arduino ? Drawing shows no connection ...

[camilo.n1012]

Hi, is not necessary to connect a 910 ohm resistor on pin 9 (col 4), will read it anyway the pin. Good luck :D
